Hawaii has broken new ground in becoming the first state to require solar water heaters in new construction.  This policy joins an array of others employed by states and localities to develop renewable energy markets in lieu of federal paralysis.   It will not be a magic bullet with federal...

Bertrand Cambou, CEO of Spansion, has an opinion on Numonyx' push into phase-change memories: "Phase-change memory is pure marketing fluff." Although Cambou is correct that existing Numonyx phase change memories are not ready for prime time, the situation will be quite different below 32nm, which...

Moving the responsibility for residential solar PV to the local electric company is the solution to the problems facing this market and would allow it to grow at ten times the current rate.   Current state and federal tax credit programs for residential solar systems are not...

There is still a tremendous bias to find "the" answer to the challenge of providing cleanly, affordable and secure energy that is also profitable to investors.  Our centralized, command-and-control way of extracting and delivering non-renewable energy blinds us to the fact that even there, different...

As the LA Times article describes, solar thermal electric generation schemes have actually been technically successful for some years and the 354 MW of parabolic trough systems built in the late 1980s are still running very well.  What's needed now for these technologies, collectively known as...

A call for a revolution in how we use energy is overdue.  But the "real" revolution will come when we learn as a society how to harvest it, not mine it.  That means going with renewables and efficiency, not traditional nuclear and fossil fuel systems that are just more of the same, and more...

The reasons why Big Oil does not invest significantly (say, 10% or more of their revenues) in solar and wind power is not conspiratorial.  It is more in the cultural makeup of an organization that is used to doing business largely one way (selling a consumable item) versus one that lasts a long...

The annual US Department of Energy report on wind power spells out details on the American achievement of 5,329 megawatts (MW) of capacity in 2007, the largest increase of any one country, and placing the US ahead of Spain and behind Germany in the Number 2 slot.  The report, issued by Lawrence...

Ersol, a small, medium priced photovoltaic manufacturer, has been acquired by the German auto giant Bosch Group.  This acquisition will be good for both parties, giving ersol deep pockets and enabling Bosch to combine photovoltaic system with its solar thermal business.  One interesting question...

The importance of this artcle can be summed up in the observations that are pointed out by various voices of a Hyper-Inflated World economy, due to these spiralling costs of crude oil. These cost increase are having a major impact on society as a whole in theoil consuming nations around the world;especially...
